Wind energy is increasingly seen as a sustainable alternative to fossil fuels, as it contributes to a reduction in greenhouse gas emissions. However, the rapid expansion of wind farms has raised concerns about the impact of wind turbines on wildlife. A new study provides comprehensive data on how turbines affect bird populations. The study suggests ways to mitigate negative effects through wind turbine design and placement, recommending taller turbines, shorter blades, and placement away from bird habitats.

Evening gowns with interwoven LEDs may look extravagant, but the light sources need a constant power supply from devices that are as well wearable, durable, and lightweight. Chinese scientists have manufactured fibrous electrodes for wearable devices that are flexible and excel by their high energy density. A microfluidic technology was key for the preparation of the electrode material was a microfluidic technology, as shown in the journal Angewandte Chemie.

Scientists at Tokyo Institute of Technology (Tokyo Tech) conducted an in-depth study on how carbon nanotubes with oxygen-containing groups can be used to greatly enhance the performance of perovskite solar cells. The newly discovered self-recrystallization ability of perovskite could lead to improvement of low-cost and efficient perovskite solar cells.

The art of croissant making has inspired researchers from Queen Mary University of London to find a solution to a sustainable energy problem.

In a discovery that could lead to the development of novel catalysts that do not rely on expensive rare metals, scientists from the RIKEN Center for Sustainable Resource Science have shown that the optimal binding energy can deviate from traditional calculations, which are based on equilibrium thermodynamics, at high reaction rates. This means that reconsidering the design of catalysts using the new calculations may be necessary to achieve the best rates.

Scientists have estimated the emissions intensity of carbon dioxide and other air pollutants from a major electricity distributor and highlighted key consequences - essential information for policymakers shaping decisions to reduce electricity system emissions.
